Abstract
Cooperative communication is the key technology for the signal processing, especially for the interference coordination. On the other hand, Dempster-Shafer (D-S) evidence theory is a branch of mathematics, which concerns the combination of some empirical evidence to construct a coherent picture of reality. To coordinate the different signal, base-stations in wireless systems are connected by a backbone network, which can help information exchange through the network between the base-stations. In this paper, we introduce the evidence theory to the problem of joint detection in the cellular cooperation networks. Taking advantage of multiple information sources, more reliable decision statistics can be achieved. Distributed multiuser detection algorithm is proposed with local passing information among neighbor base stations, and the performance is compared in terms of error rate. Simulation results verify that the proposed method outperforms conventional detection algorithms.
